Unusual metals may explain how Earth’s magnetic field formed

The magnetic field of Earth is created by a dynamo effect, but scientists do not fully understand how this is possible. A recent study suggests that strange metals, called Weyl metals, could generate the dynamo effect that creates the magnetic field.

The behavior of these metals is governed by topology and their electrons move bizarrely as if they had no mass. The scientists calculated that it should be possible to create a dynamo from solid Weyl metals.

The study is purely theoretical. However, there are plans to test the hypothesis by creating a Weyl metals dynamo in the lab to better understand the magnetic field.
